Meet Yvonne Treen

Yvonne’s career is built on extensive experience in industrial relations, generalist HR roles, general management, sales and marketing, procurement and P&L operations functions across large corporates.

As co-founder of the Ripasso Group, Yvonne has worked across a wide range of clients in three key areas: change management, coaching and leadership development. She is a specialist coach in dealing with individuals and teams in conflict, and more particularly rehabilitating leaders whose behaviour is seen as highly abrasive. Her passion is supporting emerging female leaders to take charge of their careers.

Yvonne has in-depth experience in assisting teams and organisations with change management. She has provided organisational development support to national and iwi-based kaupapa Māori organisations.

She is an experienced speaker at among others the 2016 International Association of Bullying and Harassment’s International Conference, HR leaders’ conferences, as well as the ICF New Zealand Conference on Conflict Coaching. Her main focus: to develop a success mindset and constructively handle unconscious bias in the workplace.

“Overall fantastic and very enjoyable (course). I will be able to apply what I’ve learned at work and make a real change. Yvonne kept my attention the whole time with good/real examples. Good mix of theory with exercises to help demonstrate. Very interesting.”
